I think that AMP made Google's search results feel like they were essentially just Google's own pages. Because that's exactly what the user sees in his address bar, when he visits an accelerated mobile page: google.com/amp/<...>. And that encourages him to hit "Back" as soon as he is done with it, instead of checking out the newly discovered website. Because he never felt like he had discovered anything. He never felt that he had left Google. The fact, that there are no AMP pages in Google's search results on Firefox Mobile, was the final reason for me to make the switch. I feel like I am browsing the world wide web again, not just a Google's snapshot of it.
